英文摘要
A structured model predicts that stabilization of mRNA combined with suppression of cell growth enhances the protein production rate of mammalian cells. We confirmed this prediction experimentally as follows.1. Choosing antibody as an example of ehich the mRNA was stable we confirmed that the mRNA accumulated in cells and the protein production rate per cell increased at the same time as the growth rate of the cells decreased.3. Addition of caffeine or interleukin 6 into culture medium was the best method to suppress cell growth rate for enhancing the protein productivity.2. We tried to stabilize mRNA of mouse interleukin 2 which is an example of unstable mRNAs by deleting AU rich region at the 3' untranslated region. Mouse myeloma cells transfected with the modified mRNA produced enhanced amount of the interleukin.
